Doesn't negate the point at all.
I'm speaking in generalities, and it's true to say that if your game is like Ben Arfa's (ie dribbling with the ball at pace), you are more likely to be on the end of tackles which can cause you injury. By and large, you're in possession more, tackles are easier to miss time and the impact will be greater.
Messi is a much better player, plays in a much better team (passing options) and plays in a league where that sort of player is given much more protection from the type of tackles that have laid up Ben Arfa.
Tbh like, when you're trying to expose flaws in an argument, it's rarely a good idea to use the world's best player as your point of comparison.
especially when you consider that Messi does tend to get the absolute shit kicked out of him, hes been one of if the not most fouled player in the champions league for the last few seasons but a mixture of luck and his supreme ability to ride tackles carries him through
